SURFACE CONDENSER.

Application filed July 17, 1925, Serial No.

Fig. 2 a section along the line 22 of Fig. 1,

Figs. 3 and 4 show a second embodiment in views similar to Figs. 1 and 2,

Figs. 5 and 6 show a third embodiment. In the embodiment of Figs. 1 and 2 A denotes the condenser casing which has a rec-' tangular cross-section and in the upper part of which are disposed the condenser tubes B. The condenser tubes are arran ed in groups and fastened b their ends mthe side walls a and a o the condenser casing. The condenser tubes open into chambers C and D which are attached to the side walls a and a of the condenser casing. The chamber C is connected with the ex; haust steam conduit E, while the chamber D receives the water of condensation which flows throu a pipe F to a collecting tank (not shown? Arran ed above the condenser tubes B and exten ing in the same direction as the same are pipes G with apertures 9 through which the cooling water trickles down over the condenser tubes. The cooling water accumulates on the bottom a of the condenser casing A and flows off through a pipe H. The casing wall a has. connected to it a pipe J for the admixion of cooling air. The cooling air is carried oflt through a pipe K which is connected to the cover a o the condenser casin A. The s aces between the tubes B are filed up by lling bodies L with a large surface, such as e. g. pipe-pieces or spirally wound strips of sheet metal. The filllng bodies L rest on screenlike plates M which are carried by the upper layer of the groups of tubes formed by the condenser tubes B.-

If the condenser tubes B are arranged sufficiently close to each other, the filling bodies L may be laiddirectly on the upper layer of the groups of tubes. T'h'e condenser tubes B may also be uniformly distributed in the 44,403, and in Germany August 14, 1924.

scription of the general operation of the condenser does not seem necessary.

The area of contact between the cooling water and-the cooling air is essentially enlarged by the filling bodies L so that the delivery of heat to the cooling water takes place in a considerably higher degree than in the case the cooling water trickles simply over the condenser tubes. Therefore, the efiiciency of the condenser is materially. -increased'by the described arrangement without it being necessary to change the dimensions of the condenser.

In the embodiment shown in Figs. 3 and 4 a screen 0 vis arranged immediately above the water distributing pipes N, which {has likewise put on it a layer of filling bodies P. By these filling bodies the cooling air is forced to deliver again the water which has been carried along with it from the condenser.

In the embodiment of Figs. 5 and 6 a screen R is arranged immediately above the uppermost row of condensertubes Q, and filling bodies are put thereon up to a level such as to cause the water supply pipes T to be surrounded from all sides bythe filling bodies. This arrangement results in a very uniform distribution of the coolin water. At the same time water is prevented thereby from being carried out with the cooling air leaving the condenser.

Clalms:

1. A surface condenser, comprising a nest of spaced condensing tubes, means for sup- T plying a cooling liquid and bringing it into contact with the tubes, and filling bodies of lar e surface filling the spaces between said tu es.

2. A surface condenser, comprising a plurality of, condensing tubes, means for supplying a cooling liquid and bringing it into contact with the tubes, the tubes being arranged in superimposed groups and the spaces between t e groups filled up with filling bodies of large surface, and means for conducting a current of air upwardly through said groups of tubes.

3. surface condenser, comprising a plurality of condensing tubes, sprinkler tubes bringing cooling water into contact with the condensing tubes, the spaces between the condensing tubes and the space above said sprinkler tubes being filled up by filling bodies of large surface, and means for conducting a current of air upwardly between said tubes.

4. A surface condenser, comprising a plurality of condensing tubes, sprinkler tubes bringing cooling water into contact with the condensing tubes, the spaces between the condensing tubes and the space surrounding said sprinkler tubes being filled up by filling bodies of large surface, and means for conductim a current of air upwardly between sald tu es.

5. A surface condenser, comprising a plurality of condensing tubes arranged in superimposed groups, sprinkler tubes bringing cooling water into contact with the condens ing tubes, the spaces between the groups of RUDOLF LORENZ.
